璇︾粏瑙ｉ噴锛氣�渉ttp://stackoverflow.com/questions/13834999/storyboards-vs-the-old-xib-way鈥�

绛旀: The reasons for liking Storyboard:There are things you can do with

a storyboard that you can't do with a nib. A storyboard lets you create segues

between view controllers, and it lets you design table view cells in-place. One

big advantage of Storyboard is the ability to view your entire application's

GUI锛堝浘褰㈢敤鎴风晫闈級flow. Zoom out and you can see how everything interconnects andflows.

The reasons for liking Xib : There are

things you can do with a nib that you can't do with a storyboard. In a nib, you

can create references to the File's Owner placeholder锛堝崰浣嶇锛�. You

can create multiple top-level views, edit them, and create connections between

them. See this answer for an example of why you'd want to do that. You can add

external锛堝閮ㄧ殑锛塷bject placeholders (a rarely-used feature寰堝皯浣跨敤鐨勫姛鑳�).

1.Apartfrom the historical value in the xib approach, xib's also provide modularity.Perhaps you have a library of code or wish to share a useful widget you made.Taking the xib approach would facilitate that sharing and reuse.

2.Thexib approach also allows you some greater flexibility in terms of your owncode.

3.Withxibs, while the modularity is nice, it's tougher to envision how everythingconnects and flows together. This can be a useful feature for yourself, or ifyou have a larger team to share with, to allow others to see how the app flows.
